IN for results! What fuel are you using? What are your baseline numbers?

Let me advise that there will be haters, doubters, internet know-it-alls, and toooooooooners, that will likely derail, side track and hi jack your thread.

It's not IF it happens, it's WHEN it happens.

PLEASE continue to update and disregard these douches. I'm am interested in the results in regards to your tuning abilities. I'm already familiar with what the Boss IM brings to the table.

Kris, did you port the Boss IM at all? From what I understand there is power to be had from a light port job.

Self made cat deletes, do tell us more. :)
Well, I will be making my own cat deletes that will make my exhaust 2.5" from the factory manifolds to my mufflers. The cat deletes will be welded to my x pipe and will have "v band" clamps to section the deletes to the x pipe. Should turn out real nice. I may make a few of them and sell them, we shall see.

IN for results! What fuel are you using? What are your baseline numbers?
93 octane 10% ethanol. I will share numbers once tuning is complete.

I appreciate it. Oh I'm expecting some hate somewhere for sure. That's why I will try to be as informative and thorough as possible to avoid nay sayers.

I have not. Upon receiving the Boss manifold, I noticed several things that could be done to improve it. I wanted to take a fairly untouched manifold to do my testing with, and since it was such a breeze to install, I will remove it, modify it, and test that as well at a later date.

Awesome can't wait to see what you come up with! I'm leaning toward a ported Boss IM the more I read.

Do you guys think that the stock internals and fuel pump can handle over 7500 rpm? I'd like to maybe consider doing this myself

I'd do billet oil pump gears with those RPM's. Bottom end will be fine

I'm just going to say that the Roadrunner engine has the same oil pump gear's and that rev's to 7500-7700 stock.

Only difference is the 2015 coyote I've heard gets valve float at 7500 rpm though so not sure how much more it should go. Hopefully I'm wrong.

It shouldn't. I could be wrong, but I believe the 2015 Coyote has the same valve springs and retainers as the Boss, or at least similar. Considering the 2015 has more aggressive intake cam and same exhaust cam, I'd say its similar.
